Thanks for your opinion on the waves, Larb. Maybe I'll try to find a way to do a batch-wave-making. They're hand-painted so they take a bit. I'm glad you noticed the climate incongruity, however, this map is aproximately placed like the United States or the middle-east/Europe, so the north isn't all that chilly. The reason for the local snow and ice is a Narnia-style (though I cringe in making the comparison) magic side-effect created when a massive spell used too much energy. Thinking about it now, I may lower the diameter of that area...
Thanks for the comment!
